The present invention relates slicing ma chines of the type in which the substance to be sliced ismovedpast a slicing knife where{ by slices are cut in successionfrom the substance, the carriage beingprovided with bearings mounted on one or more guides fixed to the base ofthe machine. One object of this inventlon a lubricating means so that the bear ng surfacesot the guides may be efliciently lubri,-'

. cated.

" hereinafter the novel featuresand' combi-' nations being set forth in the appended Another object of this invention is to provide a reservoir for the lubricantinclose proximity of "the guide so that the lubricating device may scoop oil therefrom and s ply it. to the bearings on the guides;

Anotherobject of this invention is to provide a means-whereby a lubricant is automatically supplied'to the bearing surfaces".

' ing surfaces.

Other objects of the invent-ioniwill'appear claims; s In the drawing is Fig. 1 is a side elevation of az-portion of aslicing machine embodying my invention; with parts thereof in section; f i 1 cross-sectionthrough the bearing,' guide, and lubricant Fig. 2' is a longitudinal holding tr g .Fig. 3 is a fragmentary end view ofone' of the bearing members, withIthe lubricant- 5 5 is airagmentary longitudinal section of the device shown in Fig.4;

Referring'to Figs. 1 to 3, inclusive; the

. deviceyas-illustrated comprises a base *1", a

is to provide shown. The supports 7 onthe-crossslide 6- carry'jtheclamp 8-which is manipulated by the "handle 9. to clamp the material to the cross-slide. Beneath each of the guide rods 4 is located a trough .orreceptacle llffora 111-,

. bricant 17 and this trough is bolted to the base 1 as at '12 and has a'cover 13 with a longitudi-' by means of screws, or the like.

Each of the bearings 3 has a spiral groove 14 located .on-its inner surface adjacentthe guiderod. Tubular members 15'are screwat opposite ends thereof. and each isj adapted tocommunicate with one end of the groove 14 to form a, continuous passage from the open end ofone tubular member through the bearing to the open end of the other tubular memher; I The tubular members 15 extend below the surfacejof the lubricant17 in the trough 11, and as the carriage recipnocates on the guide rods 4 the. lubricant is forced through the passage formedby the tubular members 15 and the groove 1 1 first in one direction and then in the opposite direction; This dis-' tributes the lubricant along the rod'andbfur-j nishes a very efiicient and durable construction for keeping the bearing surfaces' well I lubricated at all times withoutthenecessity ofusinga greatnumber of parts or special lubricating devices which require constant attention. g of this'kind isto fill thetroughs 11 with a lubricant, as needed. v r

,.-It will be noted that as the carriage 2reciprocates'a. suction is created in one of the tubular members 15 and that 'a pressure is built up inthe other tubular member. Both of these .forces therefore assist each other in carrying theilubricant through the groove under each .of the guide rods and that any suitable mechanism may be used to reciprocate thecarriage. A very common means for V (lOlIlgthlS belnga crank and 'pltman connec- I tion to the table which is operated by a, tatingshaft; a i I In Fig. 4, is shown a modification in whichv All that is. necessaryfiin devices the tubular extensions from the groove are made integral with the bearing member, the device as illustrated here showing the base 1 and the guide 4: supported by the bracket 5, the same as in the embodiment shown in 1 to 3, inclusive, but in this instance the carriage 2 has a bracket 19 carrying a bearing 20 fastened thereto which slides on the guide 4. The bracket 19 also has pivotally connected theretoa pitman 18 usedto reciprocate the carriage in a well-known manner. The trough for the oil in this instance comprises a tubular member 21 surrounding the guide rod 4 and carried by brackets 22 mount ed on the rods 4 and has a slot 23 through which a portion of the bracket 19 is adapted to-extend so as to provide a connection to the bearing 20. V

The oil groove 24: on the inner surface of the bearing 20 is similar to the groove 14: shown inFigs. 1 to 3, inclusive. Cast integral with the bearings 20 are the tubular members 25, the openings of which are in communication with the groove 24 so that as the carriage is reeiprocated the oil or other lubricant is forced through the groove in the same manner as in Figs. 1 to 3, inclusive.

This modification also has the advantage of having a covering means for the guide rods throughout substantially its entire length, this covering consisting of the upper portion of the tubular member. It is very important that dust, dirt and other forelgn matter be kept from falling upon the guide rods so as not to contaminate the surface of the rod and injure the bearing surfaces of the rod and the bearing on the carriage, and the covering means just described is very efficient for that purpose. It is understood, however, that the slot 23 may be in other positions around the periphery of the tubular member 21' and still be within the spirit of the present invention,

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended and I wish therefore not to be restricted to the precise construction herein disclosed.

Having thus fully disclosed an embodi ment of my invention. what I desire to secure by Letters Patent of the United States is:

A slicing machine comprising a base, a guide on said base, a table adapted to reciprocate above said base having a bearing co-operating with said guide, a groove in said bearing, a lubricant trough, and extensions on said bearing having openingscommunieating with said groove, said extensions adapted to extend into the lubricant carried by the trough to convey the lubricant to the groove as the table reciprocates.

2. A slicing machine comprising a fixed guide, a bearing on said guide supporting bers, and a tubular member on each of said slide members having an opening therein communicating wlth said groove, and a trough for holding a lubricant, said tubular members being adapted to scoop the lubricant from said trough as the table reciprocates.
